  • Patent number: 7655031
    Abstract: An expandable stent and delivery system is provided for treating body vessel defects, such as partially occluded blood vessels and aneurysms. The delivery system includes a core member having a non-cylindrical retraction member with extending portions configured to extend between struts of the stent. The stent includes enlarged anchor members that cooperate with the retraction member to secure the stent to the core member for movement within a delivery catheter and deployment to a body vessel defect. The extending portions provide a greater contact area than would be possible with a cylindrical retraction member, which is especially beneficial when retracting a partially deployed stent into the catheter.

  • Publication number: 20100010415
    Abstract: A valve for use in a shunt system to drain fluid from one part of a patient's body to another is provided. In an exemplary embodiment, the valve is operable at a threshold pressure that is selectively adjustable up to at least about 400 mm H2O at increments in the range of about 10 mm H2O to 40 mm H2O. The ability of the valve to operate at a high threshold pressure and to be adjusted at relatively small increments renders the valve particularly advantageous for use in younger hydrocephalus patients. In particular, the operating pressure of the valve can be gradually limited in small increments over a period of time to slowly force the patient's own resorption system to circulate cerebrospinal fluid. At high operating pressures of at least about 400 mm H2O shunt independence can be achieved thereby allowing the shunt to be successfully removed.

  • Patent number: 7611530
    Abstract: A medical device having at least one expandable stent, and at least three removable slat members carried by the stent. The removable slat members provide a substantially continuous cover for the medical device, and thus impede the flow of blood through the peripheral walls of the medical device. When deployed within a blood vessel, some of the slat members may serve to cover an aneurysm and restrict the blood flow into the aneurysm. In addition, one or more of the slat members may be selectively removed to provide blood flow into a branching blood vessel. In an alternative embodiment, an inner expandable stent is coaxially disposed within the outer expandable stent, and three removable slat members are carried by the inner expandable stent.

  • Publication number: 20090269413
    Abstract: Flowable graft materials are provided which comprise collagen powder and a liquid in an amount sufficient to impart a flowable consistency to the material. The graft materials are sufficiently formable and pliable so as to provide both superior contact with and easier access to a surgical site than typical, more rigid grafts such as collagen sheets. These flowable materials may also be in a fluidized, paste-like and/or gel-like state and may be moldable and/or ejectable. The flowable collagen materials reduce and/or eliminate post implantation problems associated with other materials, e.g. synthetic dural sealants (hemostasis products), such as product swelling after application and implantation. The flowable graft materials are particularly useful as a dural graft.
